Very simply.

That is the implementation of cppcms::application::main(std::string)
exactly according to this description

void application::main(std::string url)
{
   if(!dispatcher().dispatch(url)) {
       response().make_error_response(http::response::not_found);
   }
}

So just reimplement it the way you want.

Additionally you can just do following:

  dispatcher().assign(".*",&myclass::my404,this)

And make sure it is the last URL you add to the list.
